OPEN-'BLLIEIO PNEUMATIC-TIRE SHOE.

Locmaria.

Specicatioii of Letters Patent.

Application led March 72 1910. Serial No. 547,719.

all whom t may concern: l

.Be it known that I, CHARLES S. SCOTT, a citizen of the United States, anda resif dent. or' Cadiz, Harrison county, Ohio,have

vinvented a new and useful Improvement in GpenBellied Pneumatic-Tire Shoes, ,of which ,the following is a specification.

The type of tire-shoe now used on automobiles is composed of three or more layers of canvas or other textile-fabric supplied with a rubberl cover `for the tread portion. Heretofore the layers of fabric have been secured together bya rubber cement which has been hardened in the vulcanizing proce'ss to secure thelayers to eacli' other. This hardened rubber makes the tire hard and 'unresilient In case of accident, a. crack or break in one 'layer of fabric .will tend to carry thro-ugh t) adjacent layers; If dirt seeps in between the. layers, it will keep working `between them, cut themapart and. `permit rotting, until there is `no connection between the surfaces. Besides, the cement or friction, as 1t is called, for connecting the layers of -fabric must be made o-f 'pure rubber and is expensive. rI avoidvall these vobjections by connecting the several layers stitches to which it comes. Then, too, the stitches last with age, whereas rubber cement deteriorates and loses its cementing quality. Finally, the processof making the stitched tire is cheaper and simpler than that of connecting the layers of such a. tire by a sticky cementwhich has to be put into the vulcanizing mold quickly.'

Intlie drawings,-the figure shows a sec- .tional perspective of an open-bellied pneumatic tire-slice embodying my invention, par-t of the rubber covering being broken away.

. It will be seen that my tire-shoe is shown y as composed of six layers of fabric A, which are sewn together by stitches B. -Since these stitches are diagonal and crossfeach other, it is clear that someof them may be vlooked .upon as llongitudinal and others as transverse in direction.` JIn fact I preferablyuse .intersecting sets of oblique stitches forming a quilting.

While I have-shown my tire as being of inextensilile-edge type, it is' manifest that I may use any other known type of edge,

The rubber cover C is also secured to, the body of thetire' by stitching.

I claiinf- An open-bellie neumatic tire-shoe composed of a multiplicity of layers of fabric, and a rubber covering, secured together by 'a quilting of stitches,` substantially. as de scribed. v v

In testimony whereof I have signed my Vname to this specification 'in the presence of two subscribing witnesses.
